18. Construction Procedure for Earthen Road • Preparation of Sub-Grade: Arranging sub-grade in proper gradient & camber. • The sub-grade is rolled & watered to have OMC & compacted to MDD. • Over it, a layer of soil 10cm thick is sprayed, rolled, & finished to have required camber & gradient. • 4-5 days curing.

Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage. The earthworks created for such a purpose are often called the sub-grade or finished contouring (see diagram).

A 100m road is to be built on hill slope by cut and fill excavation. By referring to the drawings (Fig A), takeoff the quantities for excavation and filling. Calculations: Two lane road – 3.25m x 2 = 6.5m wide. Add 500mm wide paved shoulders (sidewalks) on both sides – 0.5m x 2 = 1.0m. Total width of road = 6.5 + 1 = 7.5m. Cut Area:
